Mammals and subsequently humanity may not have become dominant on earth had it not been for the global catastrophe that led to the extinction of the dinosaurs 65 million years ago.Living orders of placental mammals , be it bats, humanity, whales or camels, have as their common ancestor a small insectivore creature that went through a major phase of adaptive radiation during the Early Cenozoic Era .Primate taxonomy (see books: phylogeny, taxonomy, systematics) is in a state of flux due to the discoveries made in primate genetics.Our hominoid line, humans, gorillas, chimpanzees and lesser apes, is one among the superfamily Hominoidea.Biologists included principles from genetics in evolutionary theory during the 1920s and 1930s.Between the mid-1930s and mid 1940s geneticists, systematists and palaeontologists collaborated to create a united approach to evolution, the "Modern Synthesis".This formed the foundation of the neo-Darwinian evolutionary theory.
( Adaptive radiation is the evolution from an unspecialised ancestral stock of many different species that adapt to a variety of ecological roles (see books)).

I have integrated this web page on human evolution into an electronic text, " Nature's Holism - Holism.
Evolution & Ecology " (see its HOME PAGE .) The result is that some areas, such as the glossary are shared.
